Is this invoice generator legal to use in South Korea?+
Yes. The Value Added Tax Act of Korea mandates electronic Tax Invoices (세금계산서) for all corporate businesses and most sole proprietors above a revenue threshold. KipBill's generator produces PDFs with the required fields; submission to the NTS Hometax portal is a separate step through accredited software or the portal directly.
What VAT rate should I use on my invoices?+
South Korea's standard VAT (부가가치세) rate is 10% on most goods and services. Some supplies are zero-rated (exports, international transport) or exempt (basic foodstuffs, medical, education, financial services). Override the rate per item where applicable.
Do I need to register for VAT before issuing invoices in South Korea?+
You register with the National Tax Service (NTS) at your local tax office to receive a Business Registration Number (사업자등록증) before commencing operations. E-Tax Invoice issuance is mandatory for corporations and for sole proprietors with annual revenue above ₩100 million.
What information must every invoice include in South Korea?+
Electronic Tax Invoices require: supplier name, Registration Number, representative name, address, business type; same information for customer; supply date; sequential invoice number; description; supply value; VAT amount; and total. Electronic signature via NTS Hometax or accredited provider is required.
Can I issue invoices in a currency other than KRW?+
Yes. Korean businesses can invoice in foreign currency for international transactions. Domestic Tax Invoices must show amounts in KRW. For mixed-currency invoices, the KRW equivalent at the reference exchange rate must be included. KipBill supports KRW and 30+ currencies.
How long do I have to keep invoice records in South Korea?+
Korean law requires Tax Invoices and supporting records to be retained for 5 years from the end of the relevant tax period. Electronic Tax Invoices are stored in NTS Hometax but businesses should maintain their own copies.
